A highly sensitive, selective colorimetric and fluorometric molecular probe based on a subphthalocyanine dye has been developed for cyanide‐anion determination in aqueous solution. It has also been shown that a carboxysubphthalocyanine derivative can be covalently anchored to transparent mesoporous nanocrystalline high‐surface‐area metal oxide films to detect low concentrations of cyanide anion in pure water with no interference from other anionic or cationic species.
